Remainder Theorem

What is Remainder Theorem?

According to Remainder Theorem, for any polynomial p(x) (whose degree is greater than equal to 1) when divided by the linear polynomial (x – a), the remainder is always p(a). 

Who Invented Remainder Theorem?

The credit for inventing remainder theorem goes to Chinese mathematician Sun Zi and the it was completed by Qin Jiushao in 1247.

What is the Use of Factor Theorem?

Factor theorem is used to find the factors of the given polynomial. For any polynomial f(x), x-a is the factor of the polynomial f(x) only when, f(a) is zero.

What are Applications of Remainder Theorem?

Remainder theorem is widely used to find the remainder of the polynomial without actually performing the long division and remainder theorem along with factor theorem is widely used to solve the polynomial equation.

What is Remainder Theorem Formula?

For the polynomial p(x) when divided by the linear polynomial (ax+b) the Remainder Theorem Formula is 

p(x) / (ax + b)

Remainder = p (-b/a)



Remainder Theorem

Remainder Theorem is the basic theorem used in mathematics which is used to find the remainder of any polynomial when it is divided by a linear polynomial. The remainder theorem works on the principle of Euclidean Division Lemma.

But the remainder theorem also has some limitations, i.e. it works only when a polynomial is divided by a linear polynomial, else it fails. The remainder Theorem is exclusively mentioned for Class 9 students. Now let’s learn about the Reminder theorem, its proof, and others in detail in this article.

What is the Remainder Theorem?

Remainder Theorem states that for any polynomial whose degree is greater than or equal to 1 if it is divided by a linear polynomial p(x) such that p(x) = (x – a), the remainder of this division is always equal to p(a). This theorem is very helpful in finding the remainder of the polynomial without actually performing the division. The remainder theorem can be easily expressed as, for any polynomial p(x) { degree greater than or equal to 1} if divided by any linear polynomial s(x) = x-a the reminder is always p(a) such that,...

Summary – Remainder Theorem

The Remainder Theorem in algebra establishes a direct connection between polynomial division and polynomial evaluation. It states that when a polynomial P(x) is divided by a linear polynomial x – a, the remainder is equivalent to P(a). This theorem simplifies polynomial evaluation by allowing one to find the remainder of a division by directly substituting a value into the polynomial. Consequently, it is frequently employed to determine roots of polynomials and to factorize them efficiently. Together with the Factor Theorem and synthetic division, the Remainder Theorem plays a crucial role in polynomial manipulation and problem-solving across various mathematical contexts....
